Hey I have an FMF system I bolted my flange then pushed the FMF pipe on onto it then used a spring and connected it to my frame so it holds tight. Did yours come with a spring??
My 05' Yamaha Blaster will run, but in high rpms bogs out and pops loudly. I tried to start it the other day and it idled for a second then made a very loud POP noise then the engine died. Any ideas?? Do I need a top end rebuild?
